技术定义与适配语境
典型 风管连接环 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A duct connection collar is a precision-engineered component designed to connect two sections of ductwork in industrial ventilation and exhaust systems. It typically consists of a cylindrical or rectangular sleeve with flanges, gaskets, and fastening mechanisms to create a sealed, rigid joint that prevents air leakage, maintains pressure integrity, and allows for thermal expansion and vibration dampening in systems like hood capture inlets.

定义
A duct connection collar is a precision-engineered component designed to connect two sections of ductwork in industrial ventilation and exhaust systems. It typically consists of a cylindrical or rectangular sleeve with flanges, gaskets, and fastening mechanisms to create a sealed, rigid joint that prevents air leakage, maintains pressure integrity, and allows for thermal expansion and vibration dampening in systems like hood capture inlets.
工作原理
The collar works by mechanically clamping or bolting two duct ends together using flanges, with sealing gaskets compressed between surfaces to create an airtight barrier. It maintains alignment, transfers mechanical loads, and accommodates minor misalignments while ensuring smooth airflow with minimal turbulence or pressure drop.
材料
Galvanized steel (common)stainless steel (for corrosive environments)aluminum (lightweight applications)with EPDM or silicone gaskets for sealing.
Flange Type
Slip-on, weld-on, or angle ring
Leakage Class
L1 (EN 1507)
Diameter Range
100-1000 mm
Pressure Rating
Up to 2500 Pa
Temperature Range
-20°C to 120°C
标准
ISO 5801DIN 24194ASHRAE 120
